Title: Fluorescent spectral differential measurement of a substrate coating
Inventor: HARKLAU LANNY L
IPC: G01N21/64
Filed: 1995-02-08
Abstract: A fluorescent spectrophotometer (100) measures the fluorescent characteristics of fluorescent probes within functional compositions of a specimen. The fluorescent spectrophotometer (100) emits light appropriate for exciting the fluorescer or fluorescers contained within the specimen. The excited fluorescer emits within an emission wavelength spectrum. Fluorescers having a narrower wavelength region over which an abrupt change in emission intensity occurs are chosen for use as a fluorescent probe. The fluorescent spectrophotometer (100) detects the change in intensity through this narrower area and performs a derivative calculation on the intensity curve. The fluorescent spectrophotometer (100) is able to distinguish the fluorescer from other fluorescers or interfering fluorescent background.

Patent CA-2184972-A1 (CA)
Inventor: OHTSUKA MASATAKA
IPC: H01Q13/18
Filed: 1996-09-06
Abstract: An antenna apparatus, a method of manufacturing the same, and a method of designing the same,  are provided.   A first dielectric layer, first dielectric film, second dielectric layer and second dielectric film are laminated on a flat metal plate in the mentioned order.   A radiation element  fed  through  a feeding line is arranged below another radiation element that is not fed through the feeding line.  The feeding line forms, along its overall length, a microstrip line having the dielectric layer sandwiched by the feeding line and the flat conductive plate, resulting  in no model  change  from the microstrip  line to  a triplate line or vice versa, with reduced feeding loss.   The thickness of the dielectric layer is so set as to be sufficiently small compared with the used wavelength, to thereby suppress the radiation  from  discontinuities  lying  on  the  microstrip  line constituted of the feeding line and flat conductive plate.  This eliminates the need for a metal shield plate to prevent unneces-sary radiation from the feeding line.
Patent CA-2186148-A1 (CA)
Inventor: VAN DE VOORDE INGRID ZULMA BEN
IPC: H04B10/272
Filed: 1996-09-20
Abstract: The method is used in an optical transmission network with a plurality of terminal stations (TS1-TSn) connected to a central station (CS) via a tree-like connection structure, to determine a signal transmission delay time between one terminal station (TSi) and the central station. The terminal stations are adapted to send cells containing information signals to the central station in dedicated time slots. The method consists of sending a start signal (start CR) from the central station to the terminal station (TSi), sending a first predetermined time interval after the receipt of that start signal, a ranging signal from the terminal station to the central station, sending a second predetermined time interval after the sending of the start signal an inhibit signal from the central station to the terminal stations to indicate that no cells may be transmitted during an idle time window; deducing in the central station the signal transmission delay time from contents of the predetermined ranging signal received by the central station during the idle time window. The ranging signal either has an amplitude which is smaller than the infomation signals contained in the cells in order not to disturb the information signals when the ranging signal is transmitted outside the idle time window, or has a similar amplitude in which case error codes are included in the cells in order to recover possible disrupted cells.

IPC: G06F11/28
Filed: 1996-12-19
Abstract: In a developing environment, a game program exists in a product ROM and a debug program exists in another ROM which is a test ROM. The debug program includes a time adjusting program and other debug routine programs.   The game program includes some statements for the debug program. When a ROM cartridge is produced as a product ROM cartridge, the test ROM is detached from the ROM cartridge and the statements for the debug program are deleted from the game program in the product ROM. The deleted area in the product ROM is left as an unusable area. However, the deleted area is very small,because the size of the statements for debug program is much smaller than the size of the debug program. Therefore, the game program is able to use almost all product ROM area.

Patent CA-2204362-A1 (CA)
Title: Recombinant alternaria alternata allergens
Inventor: LECHENAUER ERICH
IPC: G01N33/569
Filed: 1995-10-31
Abstract: The invention relates to the complete cDNA sequences of the Alternaria alternata allergenes Alt a 45 and Alt a 12. It has been possible in the course of molecular biological analysis of the allergens to identify Alt a 45 as a protein-disulphide isomerase. This protein is a 45 kD large protein to which 47 % of patients react and is thus an important primary allergen. Alt a 12 (to which 8 % of patients react) was identified as a ribosomal protein which is of interest because auto-antibodies for ribosomal proteins are found in patients suffering from lupus. It remains to be seen whether there is any connection between allergy to mould fungus and autoimmune diseases. Using this recombinant sequence and computer analysis, it has been possible to identify highly potent B- and T-cell epitopes and to use the peptides derived from the recombinant proteins for diagnosis of an allergy to Alternaria alternata mould fungus. The peptides has also proved suitable for both in vitro and in vivo allergen-specific stimulation of T-cells (proliferation, interleukin production), and for blocking the T-cells resulting in a tolerance of the allergen-specific T-lymphocytes.
